chore: Update ESLint config to v14.1.0

[Gudahtt]

Explanation

Update ESLint config packages to v14.1.0.

The rule jest/unbound-method has been temporarily disabled. This is a looser version of @typescript-eslint/unbound-method, which was already disabled. We can attempt enabling both at the same time when we're ready.

Note

Updates ESLint config packages to 14.1.0, disables jest/unbound-method, and refreshes lint warning thresholds.

• ESLint Config:
  • Bump @metamask/eslint-config, @metamask/eslint-config-jest, and @metamask/eslint-config-typescript to ^14.1.0 in package.json and yarn.lock.
  • In eslint.config.mjs, disable jest/unbound-method for test files.
• Lint Warning Thresholds (eslint-warning-thresholds.json):
  • Adjust counts and remove several entries for packages/eth-block-tracker/** (e.g., drop @typescript-eslint/naming-convention thresholds and BlockTracker.ts entry).
  • Reduce @typescript-eslint/prefer-promise-reject-errors threshold in packages/json-rpc-middleware-stream/src/index.test.ts from 3 to 1.
  • Misc minor threshold updates across packages to align with new config.
